TYPEVJRITING MACHINE.

Application filed August 21, 1923, Serial No. 658,502.

This invention relates to manifolding typewriting machines of the continuous billing type, in which a continuous composite web is fed around a cylindrical platen, the composite web comprising several plies of werk-sheets having successive corresponding forms printed thereon, said plies being sometimes separated from each other, and sometimes lioined at their side edges to form a fanfolded web, the various plies having carbon-sheets interleaved therebetween. The

invention relates more particularly te means to facilitate a relative displacing or shifting between the carbon-sheets .and the worksheets, or, in other words, a shifting of the carbon-sheets from the typed set of forms to a fresh set or untyped set of forms.

ln the Underwood continuous billing typewritiug machine shown in the patent to `Wernery @a Smith, No. 1,132,055, dated latarch 16, 1915, a cylindrical platen is employed, and said platen is displaceable up` wardly bymeans of a swingframe to permit the composite web to be straightened out preparatory to displacing or shifting the carbon-sheets along the work-sheets to a fresh sot of forms. There is also employed, in said mach-ine, a table extending rear` wardly from the platen, over which the work-web is conducted from the rear of the machine to the platen, and upon which a carboncarrier is mounted to travel back and forth, towards and away from the platen, said carbon-carrier having the ends of the interleaved carbon-sheets connected thereto, and being movable rearwardly by a handle while the work-sheets are drawn forwardly te a suitable gage; after which the platen is lowered to its normal printing condition, and the typed set of forms severed.

1n my co-pending application Serial No. 645,995, tiled June 18, 1923, provision is made to so condition the work-web that there may be a relative shifting between the carbon-sheets and the work-sheets without lifting the platen, the platen remaining als in its usual typing` position. For this puipwe, there is provided a table having a curvature of comparatively large radius. A rearward extension of said table supports a carbon-carrier to which the ends of the carbon-sheets are attached, and which may be `operated by a handle to push it rearwardly to withdraw the composite web around the platen to free the carbon-sheets from the platen, after which' the work-sheets may be fed forwardly around the platen to a suitable gage while the carbon-sheets are held. The carbon-sheets may then be fed with the worksheets until the leading'edges of the work-sheets come to a second gage when the typed set of forms may be severed, the carbon-sheets having reached the printing point.

An object of the present invention is the `provision of means to so condition the web that there may be effected a relative shifting between the carbon-sheets and the wor-lrsheets without conditioning the web to form a curvature of large radius from the platen and without straightening out that portion of the web including the carbonsheets, thus enabling the dimensions of the machine to be kept down to a minimum and producing a simple device which may readily be applied to any standard typewriting machine.

To this end, the invention comprises a rearwardly-extending table over which the work-web is conducted to the platen, said table being connected to suitable brackets on the typewriter-carriage to travel there with, and disposed with its forward end near the upper edge of the usual rear paper-shelf. A carbon-carrier is mounted to travel back and fort-h on said table, towards and away from the platen. The various plies of the web pass through the carbon-carrier, where the carbon-sheets become interleaved between the plies, whence the web extends forwardly over the rearwardly-extending table, and bends downwardlyi at the forward end of said table towards the platen. Suitable bars or separators are provided in the bend of the web at the forward end of said table, said bars being so arranged as to hold the plies of the web separated. from each other so as to avoid touching and consequent binding of the plies againstl the carbon-sheets, thus affording freedom of the carbon-sheets and permitting the work-sheets to be shifted relatively thereto around sai-d bend without sinudging. Each bar is Ieffective to guide one of the plies and its supeiposed carbon-sheet. The Ibars are detachably mounted vat the forward end of said table, and each bar is provided at its free end with an extension to 4bear against the underlying bar to thus prevent saggi-ng of said bars, which may be caused when feeding the web over sai-d bars, the lowermost bar bearing against a fixed bracket.

lith this arrangen'ient, in 'order to Vprepare the web for a worksheet-shifting operati-on, the feed-rolls are'lirst "cast off and then the carbon-carrier is vpushed"rearwardly, to withdraw the web around thepplaten to arrest the carbon-sheets with their leading edges clear of the platen. The feedrollers 'are fth'enagai'n thrown on to iafdvance lthe work-'sheets while'the carbon-sheets yare held, until Vthe leading edges ofthe worksheets ieacli a .gage arranged -at the `delivery side of the platen. The worksheets-and the carbon-sheets may then be fed around the platen together, luntil the leading edges of the work-'sheets reach a second gage, at

which time the carbon-sheets have reached the printiiig point, and the bottoms vof the `typed forms Lhave reached a knife, where when adjusted for a Vsmall form. VSaid gage is so positioned with respect tothe gage-bar, upon which it is adjustably mounted, when set for long forms, as to be beh-ind the plan-e of the `gage-bar kso as not to interfere with the leading edges'of the work-sheets while they are being Vadvanced from said `gage to the second gage. vWhen-the work- :sheet-'displacement gage is adjusted for a small or short form, it is disposed below the face of the front table so as not to interfere with the leading edges ofthe work-sheets.

V@lt-lier features and advantages will hereinafter appear.

`r`l`he invention is shown vas 'applied'to an Underwood standard typewriting machine, in which type-bars 10, when operated by lkeys, not' shown, six'iing'fupwardlyv'and rearlwai-diy to printfagainst 4the front cfa cylindrical platen 11,-mounted` on a oari'ia'ge'lQ comprising y-'end bars '13 "connected `to each vvother by a rear bar 14 'and a fro-nt baiynot shown, v said carriage being mounted for letter-feed movements on `a'rear rail 15 and a front rail, notshown, sa-id'rails` being supported on the man frame A1'6 of'thean'achine. The platen is secured tol a shaft 17 journaled in yenclplates 1S of fa platen-frame 20, said lend plates being secured yto 'each-other by a barQl and areai paper-table 22, vover which a 'composite.work-web 23 is led from the back fof the machine to'the'rlear and 'beneath the platen where 'there are provided feedyrollers 24 -an-d '25 -to assist in feeding the work-web aroundV the platen. The platen may be rotated by la linger-wheel 26 or linespace wheel 27, thezlatter being op'erableby suitable line-space lin'echanis'm, not shown. The platen-frame ris supportedlon the carriage-frame for ease-shifting movements in the usual way to present the'plfaten to lowercase types '-30 yor upper-case types 31 on the 'tyl'ie-bar-s'." 'The feed-'rollers' may be released lwardly from the platen, said table supporting the 'composite web 23, sai-d web'p'assing `over said table to the platen and being composed of work-sheets 33' with interleaved carbon-sheets 34@ therebetween. The table 32 comprises 'end bars 37 connected to each other by a front cross-bar 40 and a rear cross-bar lll) ill, and is supported to travel with the carriage l2. rlhe table 32 is connected with said carriage, for this purpose, by rearwardly-extending brackets 42 secured .to the under side of the carriage-bar lil and to the under side of the cross-bar l0 of said table. The two end bars 37 have rails 4:5 secured thereto to guide a carbon-carrier i6 in its inoivenient towards and away from the platen. rlhe carbon-car ier comprises abaseplate 47, to the under side of which are attached four rollers 4S, two at each side of the machine` to run on the rails d5. Vlhe carboncarrier further comprises stepped uprights 50, one at each side of the base-plate 47, upon which the carbon-carrying blades or holders 5l are detachably mounted, said carboncarrjing blades having' connected thereto the ar ends of the carbon-sheets 311. The workweb 23 inay be composed of separate plies, .or the plies inay be connected alternately at ir opposite sides to form a fan-fold., as .ieated inlfiggure 6. Said work-web niay be conducted from any suitable source of supply upwardly at the rear ofthe machine to a turning bar 52, supported by standards 55 and provided with suitable end gages 54: for the web. Frein the turning;` bar the web extends forwardly through the carbon-carrier, where the ,albori-sheets beconie interleaved between the plies of the web. The web is then bent downwardly at 56 in front of the table 32 towards the platen.

the bend of the work-web there is arranged C t of guide-bars 5T or separators over which the wordt-sheets are conducted, there beingl one guide-bar for each ply or I Veet 33 to thus hold the work-sheets ated from each other and consequently bii'iding' of the carbon-sheets 34 betlie work-sheets at said bend 56. rlhis tion of the work-sheets enables them c readily shi fte( relatively to the carbonl Y described.

orins has been typed, the 1 ving,` reached 4 the position V .l jure l, it is necessary to cause o.' y)lacenient or shifting' between its and they work-sheets, or., in

.n *he carbon-sheets frein the tyiied portions of the work-sheets. To this end, the feed-rollers 21land inay first be released by means of the feed-roller-re-lease ard feed the work-sheets 83 forwardly while the carbon-sheets 3st are held by the carbon-carrier. rEhe extent of this forward movement of the work-sheets is determined by a gage or indicator Gl on a gage-element 59 adjustably secured to a stati or gage-bar G2 by a thumb-screw 59u. The rave-bar G2 is secured verre:

carbon-carrier and the. pressing` together of the irbon-sheets 3ft between the` worlisheets behind the platen. This tendency is overeoine, however, during a work-sheet-shifting operation.,` by holding the carbon-carrier, as previo'L y explained. To deterinine the eX- tent of feed of the work-sheets when a fresh set of forms is being` brought to the printing 'it with the carbon-sheets, there is provided a second gage 6ft on the gage eleinent 59 to which the leading edges of the worksheets are brought, as shown in Figure 'She typed portion of the work-sheets, or, in other words, the typed set of forros, may be severed after the work-sheets have been brought to the gage @fl by drawing` thein forwardly against a knife 65 suitably mounted on table G6 supported on the crossbars G3.

rthe guide-bars 5T inay readily be assembled on the `n'iachine, and, for this purpose, they are detachably inounted on the forward end of the rearwardly-extending table 32, said table beingprovided with two blocks 70, each having an Vupwardly-eXtending standr screw Tl, the screws 7l passing 'through holes T2 in rearward este lions 7f3 of the Agnide-bars. rllhe {guide-bars arevsuperposed., and are provided with s1 acers 7a to properly space theni freni the blocks TO on the table and from each other. 'l` hey are fastened on the table by thumb-nuts 7 5 thread.- ed onto said standards Tl. rlhe free ends of the Iruido-bars are provided with downturned lips 7G, each engaging its underlying tide-bar to prevent sae-eine; of the bars, the

.which the gao'e 6l may enter when set ior M., comparativelyshort forms,` the face ot' the being tlush with or shghtly below the tace ot the table. 6G so as not to catch lon the upper 'edges ot the work-sheets as they are fed past said Y 'Io'guidc the forward end ot the web 23 as it passes through the guide-bars or spacers 5T and to the platen, and thus avoid accidental sidewise displacement ot said web, "there are provided side-edge guides S8 adjustably secured to a bar S-ZL supported on the table 32 Variations may be resorted to within the scope ot the invention, and portions o' the improvements,may be used wit-hout others.
